# Nucleotide Count

Given a single stranded DNA string, compute how many times each nucleotide occurs in the string.

The genetic language of every living thing on the planet is DNA.
DNA is a large molecule that is built from an extremely long sequence of individual elements called nucleotides.
4 types exist in DNA and these differ only slightly and can be represented as the following symbols: 'A' for adenine, 'C' for cytosine, 'G' for guanine, and 'T' thymine.

Here is an analogy:
- twigs are to birds nests as
- nucleotides are to DNA as
- legos are to lego houses as
- words are to sentences as...

## Running the tests

To run the tests, run the command `dotnet test` from within the exercise directory.

## Autoformatting the code

F# source code can be formatted with the [Fantomas](https://github.com/fsprojects/fantomas) tool.

After installing it with `dotnet tool restore`, run `dotnet fantomas .` to format code within the current directory.

## Further information

For more detailed information about the F# track, including how to get help if
you're having trouble, please visit the exercism.io [F# language page](http://exercism.io/languages/fsharp/resources).
